IMPROVEMENT IN APPLE PARERS AND CdRERS.

Specification forming part of Letters Patent No. 193,220., dated July 17, 1877; application filed May 14, 1877.

To all whom it may concern Be it known that I, WILLIAM E. BROOK, of the city, county, and State of New York, have invented an Improvement in Knives; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being bad to the accompanying drawing, forming part of this specification.

The invention is more especially designed for use in paring the rinds from fruits and vegetables, and for coring fruits but it-is also applicable to other purposes.

The invention partly consists in a concavoconvex longitudinally-slotted knife-blade, one or both sides of the slot insaid blade being formed with a cutting-edge.

The invention also consists in the provision of a cutting coring-point formed on the aforesaid slotted' knifeblade, as hereinafter set forth. Figure 1 in the'accompanyin g drawing represents a side view of a knife constructed according to the first part of my invention and without a coring-point; Fig. 2 is a transverse section of the same on the line to m in Fig. 1. Fig. 3 is a central longitudinal section of the same on the line y y in Fig. 1. Fig. 4 is a side view of a knife comprising my entire invention. Fig. 5 is a diagram, showing the operation of the knife in paring.

A is the slotted blade of the slot therein. Both sides of said slot are preferably formed with a cutting-edge, c,

which permits the use of the knife by either the right or left hand, and the cutting with either hand to or from the operator; but, if desired, only one side of said slot may be formed with such cutting-edge.

The said blade is made concavo-convex in its transverse section, as shown in Fig. 2, either by bending it on a circle or other curve, or by giving said cross-section an approxi:

mately V-shaped form, the curved form, how-.

the knife, and b ity of the blade remote from the handle, or it may terminate a short distance from said extremily. which is preferable, as the blade is .stronger when the slot does not run out at the afterparing the same, and the point is also very useful in clearing out the eyes of potatoes and narrow depressions in the surfaces of other vegetables.

The blade A is handle, B.

Although I have described my improved knife chiefly with reference to its use as a paring-knife, it will be readily seen that a knifeblade constructed as described, and fitted to a handle as one of the blades of a clasp or pocket knife, would be auseful tool for carvers or pattern-makers, and for ordinary whittling, asit would be impossible for it to cut into any material'beyond a certain depth. The use of the knife is exemplified in Fig. 5, where it is shown in position as when peeling a potato. It will be seen that the blade on one side of the slot gages the thickness which the edge on the other side may cut, and also that the convexity of the blade permits it to cut down and peel out abrupt hollows.

I claim- I l. The concavo-convex longitudinally-slotted knife-blade, having one or both sides of provided with any suitable the slot in the same formed with a cuttingedge, substantially as and for the purpose specified.

2. The concavo-convex blade, having thelongitudinal slot formed therein, with a cutting edge or edges, and provided with a cutting coring-point formed thereon, substantially as and for the purpose set forth.

In testimony whereof I hereunto sign my name in the presence of two subscribing witnesses.
